Thailand's first national park has it all: mountains, dense forest, exotic wild animals, waterfalls, lakes—the list goes on and on. Covering more than 2,100 square kilometers, the sprawling park stretches into four provinces and holds something for everyone who visits.

The park is an especially great place to see Thailand's natural glory on your way north. When in Pak Chong, the largest town close to the park, be sure to stop by the daily market, where local people sell their wares. About 15 kilometers east of the city, you'll find the beautiful Lam Takhong reservoir set in a wide valley.

Things to Do in Khao Yai National Park

1. Haew Narok and Haew Suwat Waterfalls

A trip to Khao Yai wouldn't be complete without a visit to one of several waterfalls. Haew Narok is the obvious choice, as the highest waterfall in the park (it's also a promising spot for scoping elephants, as they like this area). This three-tiered beauty can be reached by hiking a 600-meter trail; you'll find a restaurant and restrooms where the trail begins, so you can fuel up before the hike.

Film buffs will be interested in checking out Haew Suwat, a waterfall that was featured in the Leonardo DiCaprio film The Beach. Nam Tok Pa Kluai, known as the orchid waterfall because orchids surround the rocks, is also worth seeing. There are a number of other smaller and less well-known waterfalls guests can hike to as well, including Nam Tok Haeo Prathun and Nam Tok Haeo Sai.

2. Khao Laem and Khao Khiau Viewpoints

For great views of the surrounding area, visitors can hike to one of several peaks. The highest mountains, located in the southern section of the park, are Khao Laem (1,328 meters) and Khao Khiau (Green Mountain, 1,350 meters). Both can be climbed during a day tour. Paths are marked according to the level of difficulty, so check with park guides to find out which are open and safe—some can only be climbed with a guide.

3. Trekking

More than 50 kilometers of hiking trails cut through the park, crossing over grasslands, through jungles, and up to the waterfalls. Some of the trails are well maintained, and the park actively promotes the use of six specific trails, as they are safe, offer great views along the way, and are perfect for people of all fitness levels. For more adventurous folks, there are also rougher, more advanced trekking opportunities.

Visitors can choose from a basic 1.2-kilometer, one-hour loop great for bird-watchers or a 3.3-kilometer, two-hour hike that takes you to the Nong Pak Chi observation—one of the best spots to catch sight of elephants in the early morning or late afternoon. Or you can try the eight-kilometer, five-hour-long trek to the Haew Suwat waterfall, which requires hiring a park ranger guide.

4. Wildlife Watching

Wildlife at Khao Yai is the main attraction for many tourists and for good reason—with over 70 mammal species recorded within the park, this is a great opportunity to catch sight of some impressive fauna.

A wide range of creatures call the park home, including pig-tailed macaques, Asian black bears and sun bears, clouded leopards, water monitors, king cobras, pythons, and a colorful and diverse array of birds, to name a few.

Khao Yai National Park is also one of the best places in Thailand to see wild elephants—about 300 call the park home and you can hire a park ranger to take you to the areas where they congregate, including the jungle undergrowth and a massive waterhole on the grassy plains.

Wild animals can also be observed from the Nong Pak Chi tower during morning and evening hours, but also during safari drives near the grassland areas, where gaur and deer congregate to graze.

Jungle hikes are the best option for bird-watching—the park is home to four species of hornbills, banded kingfisher, pelicans, cuckoos, and many other birds.

5. Night Safaris

Night safaris are often your best chance of catching sight of elusive nocturnal animals. Just jump in the back of a pickup truck led by park rangers and head into the night to search for wildlife. The rangers will track animals through the park, and once they find one, they'll shine a spotlight in their direction.

On any given night, you can see deer, spotted civets, field mice, snakes, and more—but regardless of what you end up encountering, the drive through dark, eerily quiet dirt roads is an adventure in itself.

Night safaris last around an hour and are available at 7pm and 8pm, after the last daytime visitors leave the park.

6. Khao Luk Chang Bat Cave

Bats aren't everyone's cup of tea, but it's worth making your way to Khao Luk Chang Bat Cave before sunset to see the long cloud of the nocturnal creatures fly into the night. It makes for a spectacular, if spooky, sight, as tens of thousands of bats exit into the sky all at once. The rocky, dry road to get there is hard to maneuver, so paying a park ranger to get you to your destination is a good idea—otherwise, be prepared for a very long (but rewarding) hike.

7. Whitewater Rafting

If you happen to be in the area during the rainy season, the Sai Yai River inside the park offers some stunning class 4 and 5 rapids. Because water levels are too low during the cool and dry season, you'll need to arrive between June and October to make the most of the river—with September and October being the most popular months (but also the rainiest).

The multi-level rafting course has six rapids—from a fun Class 2 row through islets and falls to a class 5 requiring navigation through rocky crevices and strong waves. The rapids can only be attempted with a guide, and beginners will need to complete a safety briefing before attempting the one-hour raft down the river.


The small town of Pak Chong serves as a popular gateway to the famed Khao Yai National Park and the mountainous region in which the park stands. Conveniently located about 200 kilometers from Bangkok, Pak Chong and Khao Yai are easily accessible from the capital.

You can reach Pak Chong by car, taking Highway 1 from Bangkok to Saraburi, then following Highway 2. It's also possible to reach the town by train on the Bangkok-Nakhon Ratchasima line, or by bus from the Bangkok Northern Bus Terminal (approximately four hours). Once here, you'll have to find a small local bus to get you closer to the park (about 40 minutes away from Pak Chong) or get a local taxi driver to bring you to the park's entrance.

Tours to Khao Yai National Park from Bangkok

A convenient way to experience the park is to take a tour from Bangkok, such as the Khao Yai National Park Waterfall with Authentic Cooking & Market Tour. This tour offers pickup from your hotel in an air-conditioned vehicle, which will take you to the Nakorn Nayok Fresh Market to sample fresh tropical fruits and pick up ingredients before you head off to a cooking class.

After enjoying the delicious meal you've learned to prepare, you'll continue on to the park, where you'll hike to Haew Narok Waterfall, stop by the visitor's center to learn more about the park, and get stunning views of the jungle from the Km. 30 Viewpoint.

Tips for Visiting Khao Yai National Park

  • For conservation purposes, the park limits the number of visitors it allows each day making it a good idea to book your visit with a tour company at least a day in advance.
  • The best time to visit the park is between November and February, when the weather is slightly cooler and the monsoon rains have stopped. During the rainy season, trekking through the park is almost impossible because of the mud and slippery terrain (you also have to deal with mosquitoes and other creepy crawlies during this time). For longer hikes, consider starting early in the morning, when the high humidity hasn't kicked in yet, and you can often get temperatures in the mid-20s.
  • The park draws a large number of Thais and foreigners, so it is best to avoid visiting on weekends or public holidays, when the place tends to be particularly crowded.
  • Be careful of particularly "cheap" prices for taxi journeys from the park entrance; they are often only for one-way journeys. When in doubt it is advisable to rely on tour operators in Pak Chong, Saraburi, and Nakhon Ratchasima.

Where to Stay near Khao Yai National Park

While it's possible to visit Khao Yai as a day trip from Bangkok, you might want to consider overnighting at one of two campsites here for a chance to see more of the park. Conveniently, visitors can rent tents, blankets, sleeping bags, and pillows right at the site, so there's no need to lug a lot of equipment around. The park does warn that the macaque monkeys will pry their way into the tents one way or another, so it's best to leave food items out in the open, so they don't go tearing apart your bags.

If you'd rather have a comfy bed and pillow to rest your head on, there are hotels in the surrounding towns that provide easy access to the park.

  • Luxury Hotels: For luxury options, you should head to Pak Chong, where a number of resorts offer the ultimate amenities in idyllic settings. One good example of that is the Thames Valley Khao Yai resort, with elegant rooms decorated in an old-English style that come with private balconies and garden views, an outdoor pool, and a spa and wellness center.
  • Mid-Range Hotels: The Anyamanee-Khaoyai Nature Life Resort makes up for the simple (but comfortable) rooms by providing a number of nice amenities, including a large swimming pool, beautiful lush gardens, and an on-site restaurant. For a touch of luxury at affordable prices, the TonSilp Art Home offers accommodation in either deluxe rooms or bungalows, featuring colorful, artsy bedrooms with large wall murals. There's also an outdoor pool, with views over the misty mountains, landscaped gardens, and a children's playground. For a great location on a main road leading to the park, you can't beat The Vintage Hotel Khao Yai. It offers a swimming pool, free coffee, and air-conditioned rooms with private balconies and mountain views; some rooms have their own private pool.
  • Budget Hotels: For an excellent location near the train station, restaurants, and a night market, the Rim Tarn Inn in Pak Chong is a good choice. This hotel offers simple but clean rooms with air conditioning and free Wi-Fi, as well as a pool.
